Stout is a medium assault tank. It has a relatively high HP so it should always be kept in the first line to sink in all damage.
Useful for taking down light defenses with its sheer force.
If not microed well, Stouts can be easily D-Gunned, so try to keep enemy Commanders at a distance. Combine with Whistlers or artillery for a great front-line push or use large packs for raiding enemy bases. Don't forget to bring some constructors with your assault for repairing and reclaiming wrecks.
